Description

Technical Field

[0001] This utility model relates to a temperature control protector. Background Technology

[0002] When the appliance is working normally, the bimetallic strip of the existing thermal protection switch is in a free state, and the contacts are in a closed / open state. When the temperature reaches the operating temperature, the bimetallic strip is heated and generates internal stress, causing it to act quickly, opening / closing the contacts to cut off / connect the circuit, thereby playing a role in temperature control. Therefore, it needs to be in close contact with the component to be sensed, such as the inner tank of a water heater. At the same time, the existing thermal protection switch is very large, resulting in a large space occupation inside the appliance and high production costs. Utility Model Content

A push rod 200 is movably mounted inside the main body 100. The diaphragm power assembly 300 is mounted on the top of the main body 100 and is used to push the push rod 200. The diaphragm power assembly 300 includes a temperature sensing cylinder 310 and a capillary tube 320. The temperature sensing cylinder 310 is used to sense temperature, and the capillary tube 320 is connected to the temperature sensing cylinder 310. The terminal 400 is mounted on the main body 100 and is used to connect to the circuit. The terminal 400 includes a first terminal 410 and a second terminal 420. The first stationary contact 500 is riveted to the first terminal 410. The first movable contact 600 is riveted to the second terminal 420.

[0021] In use, the temperature sensing cylinder 310 is inserted into the temperature sensing space. When the temperature sensing cylinder 310 is heated, the high-temperature expanding working fluid will flow from the capillary tube 320 into the inner cavity of the diaphragm power assembly 300, causing the diaphragm power assembly 300 to push the push rod 200, causing the first moving contact 600 to disconnect from the first stationary contact 500, thereby disconnecting the circuit.

The diaphragm housing 330 is provided with a connection port, and the capillary tube 320 is welded to the connection port. The temperature sensing cylinder 310 is connected to the capillary tube 320. When in use, the temperature sensing cylinder 310 is heated, and the high-temperature expanding working fluid will flow from the inner diameter of the capillary tube 320 to the diaphragm 340, thereby pushing the diaphragm 340, which in turn pushes the push rod 200, thereby disconnecting the first moving contact 600 from the first stationary contact 500.

[0023] Reference Figure 4 According to the circuit configuration, terminal 400 also includes a third terminal 430 and a fourth terminal 440. The third terminal 430 is riveted with a second stationary contact 700, and the fourth terminal 440 is riveted with a second movable contact 800.
